Gave an Ignite Velocity talk tonight at Velocity about Apache Libcloud.
The Ignite format is 20 slides, automatically advancing every 15 seconds -- I think I did okay, though I had a few slides where I needed better timing without a doubt, but I was happy enough with it for my first presentation in that format. It definitely makes you keep moving!
Its different compared to the more traditional slideless "Lightning Talks" -- the Slides can be a hamper with bad timing for topics, but I liked that it kept you ontrack, while most lighting talks tended to get cut off early.
Anyways, I've posted slides for Apache Libcloud @ Velocity Ignite.
